MOLD-CLAMP.

Specification of Letters Patent.

Patented Juno 2, 1914:.

Application filed November 4, 1912. SerialNo. 729,442.

To (tZZ whom it may concern Be it known that I, Morris J. KILLITS, a citizen of the United vStates, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Mold-Clamps; and i do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved clamp for holding together molds for cement columns, smoke stacks and the like.

One object of the invention is to provide a clamp of this class which is adjustable to fit molds of different sizes and shapes without the use of any screws, nuts or other detachable elements, such as are liable to be lost, which may be quickly attached and detached, and in which the slack may be readily taken up.

rlrnother object is to provide a mold clamp which is absolutely safe, as after being secured cannot become loose, and which has maximum strength with minimum weight.

il-h these and other objects in view, the invention consists of certain novel features of construction, and the combination and. arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 represents a side elevation of a column mold. equipped with this improved clamp; F 2 is a horizontal section thereof on line 2-2 of Fig. 1 looking in the direction of the arrow; F 3 is a perspective view of one of the clamp members; Fig. 4 is a detail vertical section taken on line l;l. of Fig. 2. Fig. 5 is a similar view taken on line 5 5 of Fig. i.

The clamp herein shown is composed of four bars 1, detachably and adjustably connected, and all of which are exactly alike, and therefore, only one will be described in detail.

Each bar 1 is constructed of suitable metal, preferably malleable iron, and of any desired length and width, and is provided at its opposite ends with means for interlocking engagement with the adjacent ends of other bars when assembled to form a clamp. These means, as shown, comprise teeth 2 arranged transversely of one end of said bar on one flat face thereof, and longitudinally extending teeth or ribs 3 arranged on the opposite face of the other end of the bar, said ribs 3 being designed to mesh with the transverse teeth of the adjacent bar and be held in engagement therewith by a pivoted cam member 41 here shown pivoted at one terminal of said bar beyond the ribs or teeth 3. This longitudinally toothed end of the bar 1 is bifurcated, and the teeth or ribs formed on the inner face of one arm 5 thereof extend from its inner end to a point about midway its length. Th free or outer end of this arm offset inwardly, between which and the free end of the arm (3 is pivotally mounted the cam This cam l has its gripping or biting edge 7 serrated to adapt it to securely engage the edge of the adjacent bar, the transverse teeth of which are engaged with the longitudinal teeth of the bar end carrying the cam.

The operation and assemblage of the bars will be readily understood from Figs. 1. and 2 of the drawings it being obvious that four of these bars are engaged and locked together to form a clamp, and that they llllty be so positioned as to clamp either a square or a rectangular mold. The transversely toot-l ed end of one bar is passed between the. outer ends of the arms 5 and 6 of another bar and then moved inwardly between said arms to cause the transverse teeth thereof to interlock with the longitudinal teeth of the otherbar. The cam +1: is then forced inwardly and the biting edge 7 thereof engages the outer edge of the bar endhaving the transverse teeth, and thereby securely locks said bar ends together, the same operation, of course, being performed in connection with the other bars.

From the foregoiitig description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily iuulerstood with out requiring a more extended cx ilanation.

Various changes in the form, proportion and the minor detail of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as claimed.

I claim as my invention:

1. A clamp of the class described con1- prising a plurality of bars, each provided at one end with teeth extending transversely thereof and its other end having laterally spaced longitudinally extending arms, one of said arms having longitudinally extending teeth on its inner face for interlocking engagement with the transverse teeth of another bar, and a cam pivoted between the free ends of said arms and adapted o swing inwardly for locking said bars together.

2. A clamp of the class described comprising a plurality of bars, each provided at one end with teeth extending transversely thereof and its other end having laterally spaced longitudinally extending arms, one of said arms having longitudinally extending teeth on its inner face for interlocking engagement with the transverse teeth of another bar, and a cam pivoted between said arms for locking said bars together.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

MORRIS J. KILLITS.
